It is permissible to cut electrical cover plates, but it is not always recommended. While cutting a cover plate can save time and effort when installing a backsplash, wainscoting, or new trim, it may also create an unsafe situation. If the trim covers the box, it may obstruct the installation of the device. However, as long as the complete box opening is not blocked, cutting the plate should not be an issue. Plastic plates, in particular, tend to chip and crack easily, so it is recommended to use a knife or metal-cutting saw for a cleaner cut.

What You'll Learn
Plastic plates crack easily, so use a knife or metal-cutting saw
Plastic electrical cover plates are prone to cracking, so extra care must be taken when cutting them. It is recommended to use a knife or a metal-cutting saw to avoid this issue.
Firstly, remove the cover plate from the electrical outlet. This will allow you to work on it without any constraints and reduce the risk of damaging the outlet or any surrounding fixtures.
Next, you'll want to secure the plate to a flat surface. This can be done by screwing the plate onto a piece of plywood or wood with a similar thickness. Ensure the front side is facing up. Drive screws through the holes in the cover plate, tightening them enough to hold the plate firmly in place. This will prevent the need for clamping, which could potentially crack the plate.
Now, you can begin the cutting process. If using a knife, place a ruler along the line you intend to cut and score the surface of the plastic. Repeat this motion until you cut through the plate. Alternatively, you can use a hacksaw, bandsaw, or scroll saw. These tools are effective in cutting through plastic without causing cracks. When using a saw, always cut from the front to the back of the plate to achieve the best edge.
Plastic wall plates are typically made of phenolic resin or Bakelite, which is fire-resistant but brittle. Applying too much pressure or flexing the plate while cutting can lead to cracking. Therefore, it is important to work slowly and carefully when using any cutting tool.

Nylon plates are more flexible and less prone to cracking
While it is possible to cut electrical cover plates, it is not recommended. Cutting a cover plate is a sign of poor craftsmanship and can negatively impact the sale of a house. If you do need to trim a cover plate, it is better to use nylon plates as they are more flexible and less prone to cracking than plastic plates.
Nylon plates are a better option than plastic plates if you need to trim a cover plate. Plastic plates tend to crack easily, even when trimmed carefully. Nylon plates, on the other hand, are more flexible and less likely to crack. This is because nylon is a more forgiving material when it comes to trimming. When trimming nylon plates, a Dremel tool can be used, and the edges can be smoothed with a Dremel sanding bit.
Nylon plates are available from various manufacturers, with Leviton manufacturing being a leader in the marketplace. Nylon plates can be purchased in different colours, such as white, and can be used for different applications, such as single-gang GFCI cover plates.
When trimming a cover plate, it is important to consider the electrical code requirements. A cover plate is required on all devices, such as wall switches and receptacles. Trimming the plate may impact the functionality and accessibility of the device. For example, trimming the side of a plate may create an open passage to the wood stud, and trimming the top or bottom of a plate may interfere with the device yoke or retaining screw.
In conclusion, while it is possible to cut electrical cover plates, it is not recommended due to potential safety and craftsmanship issues. If trimming is necessary, nylon plates are a better option than plastic plates as they are more flexible and less prone to cracking.

Cutting the side of a plate may leave an open passage to the wood stud
Cutting electrical cover plates is sometimes necessary to allow for clearance, especially when adding a backsplash, wainscoting, or new trim. While it is possible to notch around the existing plate, cutting the plate to fit can save time and effort.
However, it is important to note that cutting the side of a plate may leave an open passage to the wood stud, which could potentially result in a fire hazard. This is because there would be no heat transfer protection. Therefore, it is recommended to use a different type of plate, such as nylon, which is more flexible and less prone to cracking.
When cutting electrical cover plates, it is important to follow the correct procedure to ensure a clean and safe cut. First, unscrew the cover plate and lay it flat on a piece of plywood with the front side facing up. Secure the plate by driving screws into the holes on the face of the plate. This will hold the plate steady while you cut. Use a sharp utility knife to score a line along the edge of the plate and then complete the cut by making repeated passes with the knife or using a hacksaw. Alternatively, a bandsaw fitted with a metal-cutting blade can be used, but it is important to push the plate slowly through the saw to prevent the blade from bending or wandering.
While cutting electrical cover plates is possible, it is important to prioritize safety and follow the correct procedures. In some cases, it may be more advisable to use an alternative type of plate that requires less modification.

Cutting the plate saves time and effort
Cutting electrical cover plates can save time and effort in certain situations. For instance, when adding a backsplash, wainscoting, or new trim, there may not be enough room for the cover plate. Instead of notching around the existing plate, cutting the plate itself is a quicker solution.
To cut a plastic electrical wall plate, first, unscrew the cover plate and lay it flat on a piece of plywood with the front side facing up. Then, drive a 6-gauge, 3/4-inch wood screw into each of the holes on the face of the plate to secure it in place. You can then use a sharp utility knife to score a line along the edge of the plate, following any marks you've made. After that, you can complete the cut with a knife, making repeated passes, or use a hacksaw or bandsaw for a smoother edge.
It is important to note that cutting electrical cover plates should be done with caution. Plastic plates tend to crack easily, so using a knife or a metal-cutting saw is safer than a wood-cutting saw. Additionally, cutting too much off the plate can impact the functionality of the device, as the retaining screw may not be accessible if the plate is notched too deeply.
While some suggest that cutting a wall plate may create a fire hazard, others argue that as long as the complete box opening is not obstructed and the modified plate does not adversely affect its safe operation, there is no violation. Nonetheless, it is always advisable to consult with a licensed electrical professional before making any modifications to electrical cover plates.

Some say cutting a wall plate is a fire hazard
While it is possible to cut electrical cover plates, some people believe that doing so is a fire hazard. This is because the plate could be made from a combustible material, such as wood or wallpaper, which could potentially be ignited by sparks from the electrical equipment.
Electrical equipment can pose a fire risk, and cutting a wall plate may increase this risk by exposing the equipment and providing a potential fuel source for any sparks or hot slag. In addition, a cut wall plate may not sit flush with the wall, creating a gap for sparks to escape and potentially ignite any nearby combustible materials.
Some builders and homeowners refuse to cut wall plates for this reason, and it is considered by some to be a violation of safety standards. However, others argue that a modified plate does not violate any codes as long as it does not adversely affect the safe operation of the equipment and does not compromise the strength of the cover plate.
To mitigate the risk of fire, it is recommended to use non-combustible materials, such as nylon, for wall plates, and to ensure that the plate is properly fitted to the wall. In some cases, it may be necessary to install an extension ring to ensure that the box is flush with the wall and reduce the risk of sparks escaping.
